Options Trading: What It Is, How It Works, and What Beginners Need to Know

Options trading in India has become a highly popular choice among retail investors, and for good reason. It is an alternative to trading shares and allows them to take part in the stock market in another way. However, it also adds another element of complexity that is a shock to many beginners.

Being prepared before you start is essential to understanding options trading. It’s the difference between using a powerful financial tool with intention and losing money to mechanics you didn’t fully understand.

This guide will provide you with information on what options are, how they work, the distinction between calls and puts, some terms you’ll encounter, some strategies you will learn as a beginner, and some of the risks you will need to be aware of before taking your first trade.

Quick Answer

Options trading involves buying or selling contracts that give the holder the right (but not the obligation) to buy or sell an underlying asset at a set price before a specified date. Call options are profitable when prices go up; put options are profitable when prices go down. The buyer pays a premium for this right. Options trading carries risks, including the loss of the premium paid when the options expire.

What Is Options Trading?

Options trading is the buying and selling of derivative contracts that give the holder the right, but not the obligation, to buy or sell an underlying asset at a predetermined price before or on a specific expiry date.

Usually, the underlying asset is a stock, an index, or a commodity. The contract specifies all of this: the asset, the price at which the contract may be exercised (the strike price), and the expiration date of the right. The most significant difference between options and purchasing stock is the word “right”.

An options contract buyer is not obligated to execute the transaction. They are buying the right to do so if it proves more beneficial.

There are two types of options contracts:

  • Call Options: Options that give the buyer the right to purchase the underlying asset.
  • Put Options: These options give the buyer the right to sell the option. We will cover each in depth shortly.

Options are exchange-traded products in India, mainly sold through the Futures and Options (F&O) segment of the NSE. Traders employ them to take a ‘view’ on price direction (with less capital than a direct investment), and investors can use them to hedge against adverse price movements in an existing portfolio.

The other party to the contract is the option seller, or the option writer. The writer agrees to perform the contract in case the buyer exercises his right, in return for the premium. There is a meaningful asymmetry in the seller’s risk profile relative to the buyer’s, which is worth knowing early on.

How Does Options Trading Work?

An options contract comprises four fundamental components: the underlying asset, the premium, the strike price, and the expiration date. Before trading, it’s crucial to understand each one.

The buyer pays the seller a premium when they buy an options contract. This is the cost of the contract, and what the buyer can lose the most. The buyer, in turn, has the right to purchase or sell the underlying asset at the strike price at any time before the expiration date (for an American option) or only on the expiration date (for a European option).

Here’s a simple example to make this concrete. Assume that a stock is available for Rs. 1,000. A trader has a ‘bull’ market expectancy. They buy a call option, with a strike price of Rs. 1,050, paying a premium of Rs. 30, with an expiry date one month away.

If the stock price increases to Rs. 1,150 before expiry, the trader can exercise their right to buy at Rs. 1,050 and immediately sell at Rs. 1,150, realizing a gain of Rs. 100 per share, minus the Rs. 30 premium paid. Net profit: Rs. 70 per share.

The stock will remain low if the condition is not met. At 1,050, the option expires worthless. The dealer doesn’t get Rs. 30 premium and nothing more. This is the highest loss to the buyer.

In-the-Money vs Out-of-the-Money

These terms describe the relationship between the price of the underlying asset and the strike price.

An option is said to be in-the-money (ITM) if it can be immediately exercised for a profit. In the case of a call option, the stock price is higher than the strike price. However, for a put option, it means the stock price is below the strike price.

If buying the option was not immediately profitable, it is an out-of-the-money (OTM) option. For a call, the stock price is below the strike. But for a put, it’s above the strike.

At-the-money (ATM) is when the price is “fairly” equal to the strike price.

Understanding the distinction between call and put options and how each responds to price movements is the logical next step after grasping these mechanics.

Key Options Contract Terms

TermSimple Meaning
PremiumThe price paid by the buyer to the seller for the options contract
Strike priceThe price at which the buyer can buy (call) or sell (put) the underlying asset
Expiry dateWhen the contract terminates, the right no longer exists.
Underlying assetThe stock, index, or commodity on which the option is based
In-the-money (ITM)The option has intrinsic value; exercising it would be profitable
Out-of-the-money (OTM)The option has no intrinsic value at the current price

Call Options vs Put Options

A call option is a contract that allows the buyer to purchase an asset, while a put option is a contract that lets the buyer sell an asset. The source of gain for each is different.

Call Options

A call option is a position held by a trader when they believe that the price of the underlying asset will rise. The call option becomes valuable when the stock price rises above the strike price before expiration. At this time, the buyer may use the option (purchase the asset at the lower strike price) or sell the contract for a gain.

Example: A trader purchases a call option of a stock with Rs. 500, paying a Rs. 20 premium. If the share price increases to Rs. 560, the option is worth at least Rs. 60, giving the buyer a Rs. 40 profit per share after the premium cost.

Put Options

When a trader thinks the price will decline, they buy a put option. The value of the put option increases if the stock price falls below the strike price before its expiration date. The buyer may sell the asset at the higher strike price despite the lower market price, or sell the contract for a profit.

Example: A trader buys a put option on a stock at a strike price of Rs. 500, paying a premium of Rs. 15. If the stock drops below Rs. 430, the option is worth at least Rs. 70, which means that the buyer has Rs. 55 profit per share after the premium cost.

The Option Seller’s Position

In the case of a call option, the seller (the “writer”) is required to sell the asset at the strike price if the buyer chooses to exercise the option. If a put option is exercised, the seller must pay the strike price for the asset. In either scenario, the seller gets the premium, but may have substantial responsibilities. One key structural aspect of an options contract is this asymmetry: the buyer’s maximum exposure is limited to the premium paid, whereas the seller’s is larger.

For a detailed comparison, it’s advisable to look into the call vs. put option guide to learn how each option works, along with examples and scenarios.

Key Terms Every Options Trader Should Know

There are words used in options trading. Before making any investments, acquaint yourself with these terms to avoid costly miscommunications.

TermSimple Meaning
PremiumThe amount of money the options buyer pays to the options seller for the contract
Strike priceThe price at which the buyer can exercise the option to buy or sell
Expiry dateThe date on which the options contract expires; unexercised options become worthless
In-the-money (ITM)The option has intrinsic value based on the current underlying price
Out-of-the-money (OTM)The option has no intrinsic value at the current underlying price
At-the-money (ATM)The underlying price is approximately equal to the strike price
Open interestThe total number of outstanding option contracts not yet settled or expired
Option chainA table displaying all available options contracts for an underlying asset across different strikes and expiries
Implied volatilityA measure of the market’s expectation of future price movement; higher implied volatility increases option premiums
Option writerThe seller of an options contract who receives the premium and takes on the obligation to fulfill if exercised

It is essential to understand open interest in options, especially for gauging market sentiment. When open interest increases alongside price, it indicates an increase in long positions; when open interest increases while price decreases, it indicates an increase in short positions. It’s one of the best market-context signals for options traders.

Please pay special attention to implied volatility. The higher the implied volatility, the more expensive it will be to buy options. The lower it is, the more affordable it will be. A trader who purchases options when implied volatility is high for the period might see that, although the underlying asset has moved in the desired direction, a subsequent decrease in implied volatility reduces the option’s value.

Understanding this dynamic, sometimes called the “volatility crush,” is important for options buyers.

Common Options Trading Strategies for Beginners

There are many types of options trading strategies, from basic options to more complex multi-leg strategies. For beginners, it is best to start with the most basic strategies.

The ideas outlined here are intended for educational purposes only and should not be considered investment advice. There is no guaranteed route to profit, and all options trading is risk-prone.

StrategyWhat It InvolvesWhen It May Be Used
Long callBuy a call optionWhen expecting the underlying price to rise significantly
Long putBuy a put optionWhen expecting the underlying price to fall significantly
Covered callOwn the underlying stock, sell a call option on itWhen expecting modest price movement, it generates income from the premium received
Protective putOwn the underlying stock, buy a put option on itWhen wanting to protect an existing long position against a price decline

A long call is usually the first strategy a beginner uses. You pay a premium and enjoy the benefits of price increases. You have the most to lose in the premium paid. The potential price is theoretically unlimited if the stock rises significantly.

A long put works in the opposite direction. You get to enjoy the advantages of lower prices at a premium. It’s also a typical initial move for traders holding a negative outlook on a given stock or index.

A covered call is an investment strategy for existing shareholders. They sell a call option on those shares and make premium income. If the stock is not above the strike price, they retain the premium and the shares. If the stock price rises above the strike price, the option can be exercised at the strike price.

A protective put is an integral part of portfolio insurance. If an investor has a bearish short-term outlook and is worried that the stock price may drop sharply, they might purchase a put option. The premium paid is the cost, and is similar to an insurance premium.

Options trading strategies are beyond these four basic approaches. For more information, read about advanced strategies such as spreads, straddles, and condors, and when and why they are employed.

What Are the Risks of Options Trading?

Options trading is risky and may not be appropriate for certain investors. These risks should not be overlooked; they are an indispensable part of preparation before trading.

Risk TypeWhat It Means
Premium lossIf the option expires worthless, the buyer will lose the entire premium paid
Time decayOptions lose value as expiration approaches, even if the underlying price does not change
Leverage riskSmall moves in the underlying can cause large percentage changes in option value
Liquidity riskSome options contracts have low trading volume, making them difficult to exit at a fair price
Seller riskIf the market swings strongly against the option writer, they may lose more than the premium they earn

One of the most critical risks of buying options is time decay, also referred to as theta. The time value is lost with every day that passes, regardless of how little the underlying asset changes. The value of an OTM option will continue to decline slowly to nothing as the underlying price remains unchanged until expiry. This is a structural disadvantage for the option buyer compared with a stockholder and does not arise if the option buyer is simply holding a stock.

Leverage risks work two ways. Options give traders the power to make a big impact on an underlying asset for a relatively small premium. The premium invested may be valuable if the trade is successful. Otherwise, all of the premium money can be squandered in a matter of moments. Many beginners are shocked by how quickly this can occur.

Seller risk is often misunderstood. The premium money seems like income, and for some strategies, such as covered calls, the risk is limited. However, naked option selling (selling without an underlying asset) can be a risky strategy with significant potential losses when the underlying asset trades heavily against the position. This is one of the worst spots in any financial market for a retail trader who is not familiar with what they have entered.

The reader should carefully consider their risk appetite. Our guide to the risks of options trading goes into more detail on each type of risk and offers examples of how they can arise.

Real-world example: An inexperienced investor purchases 10 call options on a stock, hoping that its price will increase by 5% over the next two weeks. The stock goes sideways for the first 10 days. Time decay has taken out a lot of value from the option, even with a small increase in the last few days. The stock appreciates by 3%, but by the time the options expire, the small increase is insufficient to offset the theta decay, and they expire worthless. Although the trader was pretty right about the stock direction, they ended up losing most of the premium paid.

This teaches us that timing and the speed of the move matter as much as direction when trading options.

Options Trading vs Stock Trading

Options trading and stock trading are very different types of trading and instruments with different structures, risk profiles, and uses. It is important to understand the difference first before making a choice based on your objectives.

FeatureOptions TradingStock Trading
OwnershipNo ownership of the underlying assetDirect ownership of company shares
Time limitEvery contract has an expiry dateShares can be held indefinitely
LeverageCan control large positions with relatively small capitalCapital committed reflects full position value
ComplexityMultiple variables affect value (price, time, volatility)Price is the primary variable
Capital neededLower capital to take a position of similar exposureFull position value required
Risk typeBuyer: capped at premium. Seller: potentially large lossesLoss limited to the investment amount for the buyer

Options differ from stocks primarily in the time dimension. When you purchase a stock, you can purchase it for as long as you desire. There is no specified time for investment.

An options contract, on the other hand, has a countdown. The longer the time between an option’s purchase and its expiration date, the more it hurts the buyer of an out-of-the-money option. Pressure in this instance is a factor that demands a different form of decision-making than stock investing.

Understanding the product requires a longer process than understanding stocks because options have several features that depend on the price of the underlying asset, time to expiration, implied volatility, interest rates, and dividends, all of which interact simultaneously.

This does not mean that one should not consider options, but it’s a reason to take the time to learn before taking the plunge and investing money.

How Can Beginners Get Started with Options Trading?

The path into options trading should be educational before it’s transactional. Knowing the product inside and out before real trading helps avoid the most common and costly mistakes that beginners make.

StepWhat to Do
1Get all the basics: know what calls, puts, premiums, strike prices, and expiry dates are
2Learn to interpret an option chain before choosing any option contract
3Before purchasing options on an underlying asset, understand the asset’s nature and price action
4Begin with basic strategies (long call or long put) and then work up to multi-leg trades
5Before you enter a trade, you need to know how much you’re comfortable losing
6Choose liquid options contracts on stocks with high trading volume

The ability to read an option chain is a valuable skill for any options trader and requires a bit of practice. An option chain lists all options available on the underlying security across various strike prices and time to expiration, including premiums, volume, open interest, and implied volatility. The ability to walk in one without hesitation, before trading, is a minimum competency requirement.

In options trading, it’s not just about the underlying stock; it’s about understanding it. Options are time-limited instruments, so when price action occurs, the direction it takes is as important as the price level. A trader who understands how a stock behaves around earnings announcements, sector events, or index rebalancing dates has a more complete picture than one who simply looks at the chart and picks a strike price.

Further, liquidity is one of the most important aspects to consider when choosing which contracts to trade. Thinly traded options contracts have wide bid/ask spreads and are costly to buy and sell at fair value. Identifying stocks for options trading with sufficient volume and liquidity is an important step in the process, not an afterthought.

Note: This is educational information and not financial advice.

What Is Day Trading Options?

Day trading options involves trading in and out of options contracts within the same trading session, with all trades closed before the market closes. It is a more complicated strategy and is much riskier than longer-term options strategies.

Day trading options has grown in popularity partly because of zero-day options (sometimes called 0DTE options), which expire on the same day they’re traded. These tools can achieve significant percentage gains in a short period and execute very rapidly. They also have a relatively high risk.

0DTE options are extremely volatile because time decay will be most pronounced on the day of expiry. An OTM option will either go in-the-money before expiration or will be worthless at expiration. There’s no tomorrow, and the error margin is very small.

For most beginner traders, intraday options trading isn’t the place to begin. This is one of the fastest-paced environments in financial markets due to the speed of required decision-making and the impact of time decay, with effects felt within hours rather than days, which can mean that the entire premium can be lost in a single session. It is better to gain a solid grasp of longer-dated options first, then move on to same-day-expiry options.

Day trading options is a risky strategy and is not advised for many traders and investors, especially for those who are not familiar with options mechanics and day trading.

Common Mistakes to Avoid in Options Trading

The majority of beginner’s trading losses in options are predictable. Knowing the most common trade mistakes is more beneficial than finding out by trial and error.

MistakeHow to Avoid It
Buying options without understanding time decayStudy theta before trading; know that time works against the buyer
Ignoring implied volatilityCheck implied volatility before buying; high IV means expensive premiums
Trading options on illiquid stocksFocus on high-volume, liquid contracts with narrow bid-ask spreads
Treating options as a guaranteed profit strategyUnderstand that most options expire worthless; risk management is non-negotiable
Not having a clear exit plan before enteringDefine your target profit and maximum loss before placing the order
Over-leveraging by buying too many contractsSize positions proportionally to account balance, not maximum possible exposure

The mistake that is causing the most harm is failing to account for time decay AND failing to have an exit strategy. A beginner purchases an out-of-the-money option in the hope that it will take a long time to move.

There’s no fixed exit date, and as the contract continues to deteriorate each day, they’re hoping it will recover before it expires. The position expires worthless, and the entire premium is forever lost.

For those who are in the options business, this sequence is so prevalent that it has its own unofficial nickname: “hope trading.”

The structural lesson is easy. When taking on any option positions, have a clear understanding of the price that signals a change in your opinion and sell the position at that price, and not wait for it to turn around.

The Securities and Exchange Board of India said that a large number of individual traders in the equity derivatives segment lose money because they are not adequately prepared for the complexity and risk associated with leveraged derivatives.

Frequently Asked Questions

What is options trading?

Options trading involves buying or selling a contract that gives the option buyer the right (but not the obligation) to buy or sell the underlying asset at a predetermined price by a specified date or time. It is an extra advantage given to the buyer. Options are used for speculation and hedging.

How does options trading work?

The buyer pays the seller a premium to have the option to purchase (call) the underlying asset at the strike price before expiration. If the market is in the buyer’s favor, the option becomes valuable. Otherwise, it might not even be worth exercising, and the buyer forfeits the premium.

What is the difference between a call option and a put option?

A call option is an option that gives the option buyer the right to purchase the underlying asset at a fixed price. It benefits if the price is higher than the strike price. A put option is an option that allows the buyer to sell at a specific price. It benefits from the price drop when the price falls below the strike price.

What are the risks of options trading?

The risks include the possibility of losing the entire premium if the option expires with no value, time decay that reduces the value as the expiration date approaches, leverage that can deliver greater losses when the price moves in the wrong direction, and liquidity risk when options are thinly traded. Investing in options is risky and may not be appropriate for every investor.

What are the options trading strategies for beginners?

Beginner-accessible strategies include the long call (buying a call expecting price to rise), the long put (buying a put expecting price to fall), the covered call (selling a call on shares already owned), and the protective put (buying a put to protect an existing long position). These strategies are described for educational purposes only. For a full breakdown, the options trading strategies guide covers each in detail.

What is options trading for beginners?

Options trading for beginners starts with understanding the foundational concepts: what calls and puts are, how premiums and strike prices work, what expiry means, and how time decay affects option value. Grasping the risk profile clearly (including that most options expire worthless) is as important as understanding the potential upside.

What is open interest in options?

Open interest is the total number of outstanding options contracts that have not yet been settled or expired. It’s a measure of market participation and liquidity. Rising open interest alongside rising prices typically suggests new buying; rising open interest with falling prices suggests new short positions. The open interest in options guide explains this in full.

How do I identify the best stocks for options trading?

Liquidity, trading volume, and volatility are the primary factors. Stocks with high daily trading volume tend to have more liquid options markets with tighter bid-ask spreads. The stocks-for-options trading guide covers the screening process in detail.

Conclusion

Options trading can indeed be a powerful financial tool. It can provide exposure to price movements with a known maximum risk to the buyer, offer investment strategies to hedge existing investments, and offer strategies not possible with outright stock ownership alone.

But that power comes with complexity that demands respect. Many factors influence results simultaneously, including time decay, implied volatility, strike selection, expiry timing, and risk asymmetry between buyers and sellers. When a directional call on an underlying asset is correct, but the one on the trade is wrong, it can be a losing trade.

The basic idea is to learn the calls and puts so well, know what you have to lose before you make any trades, and to begin the trading process with simple structures before complex ones. This does not ensure profitable trading, but it helps avoid the worst and most costly of errors.

The next recommended read is the options trading strategies guide, which covers additional strategies and combinations, from single-leg trades to more complex ones. It provides guidance on when and why each is used.
